Unknown natural wonders of the world – a homage to the "gentle giants".

Michel Brunner, a graphic artist and author of "Giant Trees of Switzerland", has been measuring and photographing giant trees in Europe for more than ten years. He has listed more than 2,000 trees, of which more than 1,000 are in Switzerland. (Photos: Michel Brunner and André Hübscher; selected by Rolf Amiet, swissinfo.ch)

"I love science and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awe by nature. Science is not meant to cure us of mystery, but to reinvent and revigorate it." by Robert M. Sapolsky

Our forest. He fascinates and frightens, it benefits, delights and sometimes makes troubles. Once broken in and looted, he again covered a third of Switzerland. But how much space we vacate the forest in our modern life yet? "The secret of our forest" is the discovery of a valued friend's strange and sometimes wild, with stories told in fascinating images from the forest of impressive people in the forest. And a gripping journey through four seasons.
